Investigators from the unit and the countyÂ?s deputy coroner made a preliminary evaluation that the death appeared to be from natural causes, possibly related to McGrathÂ?s history of diabetes. An autopsy will be performed this afternoon.

McGrath, 20, intended to major in business.

Timothy R. Aher, 25, a second year Notre Dame Law School student from Brookfield, Conn., died unexpectedly Sunday in Ilford, England, a suburb of London. He was enrolled in the law schoolÂ?s London Law Programme. No information was released on the cause of death.

A memorial Mass for both students will take place at 10 p.m. Tuesday in Sacred Heart Basilica. The Rev. John I. Jenkins, Notre DameÂ?s president, will preside.
